Beschreibung
The PHH-830 pH/mV and temperature meter with RS-232 communication is economically priced for many applications. The PHH-830 features an auto data hold. Pressing and holding the “test toggle” key during measurement will cause an “A” to flash and then hold the LCD. The PHH-830 also features recording of 99 records and also has an RS-232 communication for datalogging.Measuring Range pH: 0 to 14 pH mV: 0 to 1999 mV Temp: 0 to 100°C Accuracy pH: ±0.01 pH mV: 0 to 600 mV: ±(0.05%+1d) Rdg 601 to 1999 mV: ±0.1% Rdg Temp: ±0.5°C or ±0.9°F Resolution pH: 0.001 pH mV: 0.1 mV Temp: 0.1°C or 0.1°F Temperature Compensation for pH Range: Manual (MTC): 0 to 100°C adjusted by push ^ button or down button on front panel.
